UnityWebRequest isNetworkError and HttpError replacement question

hello,

so i am using the UnityWebRequest class, and i see its error is saying the isNetworkError and HTTPError is deprecated or no longer being used... so should i use error property? or is there a better way to capture if there is an error? right now I replaced it from:

Code (CSharp):

1. UnityWebRequest request;
2.  
3.                 if (request.isNetworkError || request.isHttpError)
4.                 {
5.                     errorCallback(request.error);
6.                 }
7.                 else
8.                 {
9.                     successCallback(request.downloadHandler.data);
10.                 }

the new WAY i think... but correct me if i am wrong or if there is a better way:

Code (CSharp):

1.                 if (request.error != null)
2.                 {
3.                     errorCallback(request.error);
4.                 }
5.                 else
6.                 {
7.                     successCallback(request.downloadHandler.data);
8.                 }
